General Description
PT8A260P is a mixed-signal base chip consists of 2
high gain front end amplifier, window comparators,
voltage reference, oscillator and low battery detector.
All the analog modules are well proven and fully
characterized. With another external digital ASIC such
as FPGA, customers can verify their mixed-signal
system faster and with minimum risk.
PT8A260P is packaged in 16-pin PDIP. The outputs
from op amps, comparator, voltage reference,
oscillator, noise rejection circuit and low battery
detector are provided.
1,500 gates of digital gate are also available inside
PT8A260P. Once customers verify their mixed-mode
application/system, a single chip solution can be
integrated by PTI’s factory within 8 weeks after sign
off.
Applications
PIR sensor controller
Special sensor control
Mixed-signal ASIC with analog front end
